This is the fourth version of the patchset to the Linux kernel to support
the Qualcomm Hexagon architecture. These patches have been organized like
previously in a somewhat logically grouped fashion.
A brief summary of changes from the last patchset:
* changes associated with removing pt_regs from user_context
* removal of arch-specific ptrace cases; use generic ptrace_request
* turn on CONFIG_ARCH_TRACEHOOKS
* removal of deprecated sigframe
* add magic values for libgcc signal stack unwinding
* add memory clobber to IO inlines
* use generic show_interrupts
* minor timer cleanup
* minor SMP IPI cleanup
* moved local_irq_enable in do_page_fault
These patches are available on Code Aurora:

Once again, thanks to everyone for their feedback!
